Squanto was a Roman Catholic.

In 1614, he had been captured by an English party led by Captain John Smith (of Pocahontas fame) and taken on a ship to Spain where he was to be sold as a slave. He was rescued by some Dominican friars who instructed him in the Catholic faith. He told them he wanted to return to his people in America. They helped him get to England, where he met John Slaney, who taught him English and arranged for him to get to Newfoundland. Squanto served as an interpreter between the English and the Indians and crossed the Atlantic six times.  He was never able to return to his own tribe, because they had been wiped out in a plague.
